在冷装工艺生产模式下,不合理的轧制计划将导致不必要的钢坯库倒垛作业,严重时甚至会造成轧制生产的延迟或中断.本文在已知轧制计划和实时钢坯库存堆放情况的前提下,对轧制计划设置了三种调整策略:轧制钢坯替换、轧制单元内钢坯轧制顺序调整以及计划钢坯取消轧制调整.基于调整策略,建立了以最小化调整惩罚及实施计划时的钢坯库倒垛次数的加权平均和为目标的数学模型,并结合问题特征设计了三阶段求解算法(THA).通过基于实际生产数据的实验验证,结果相对于原轧制计划,在满足轧制工艺规程前提下大量减少了钢坯库的倒垛次数,算法和模型是可行且有效的.
In cold-working process mode, unreasonable rolling plan will lead to unnecessary billet re-stacking operations, even in severe cases, will cause delays or interruptions in rolling production.This paper reports the rolling plan and real-time billet inventory Three adjustment strategies were set up for the rolling plan: rolling slab replacement, sequence of billet rolling in the rolling unit, and rolling off of the planned slab.According to the adjustment strategy, a set of adjustment strategies were set up to minimize The weighted average of the number of billets in the billet warehouse during the implementation of the plan and the mathematical model of the target, and combined with the characteristics of the problem to design a three-phase solution algorithm (THA) .According to the actual production data of the experimental verification, the results relative to the original rolling plan, It is feasible and effective to reduce the number of stacks, the algorithm and the model of the slab warehouse under the premise of meeting the rolling process.
